A wireless router is an integrated network device commonly used in small office/home office (SOHO) networks with about 1 to 10 users. section 15.4
A typical wireless router combines these functions:
- Router: forwards packets between the local network and the internet. section 15.4
- Switch: connects wired end-user devices. section 15.4
- Firewall: blocks connections initiated from the internet. section 15.4
- Wireless access point: connects Wi-Fi clients. section 15.4
- Optional modem: supports some internet connection types. section 15.4
SOHO deployment
A home or small business may use one wireless router, one internet connection, wired devices, and Wi-Fi clients. This saves cost but provides less redundancy than an enterprise network. section 15.5
